各位C语言高手们，小女子在做一个短学期课程结业设计，帮忙看一下这个程序的错误
/*篮球赛个人技术统计系统
设某篮球联赛要统计20名著名球员个人技术数据。要求用高级语言实现篮球联赛个人技术数据处理系统。该系统在磁盘上存储如下信息：
1。每场球赛的个人技术数据。一场球一个人的技术数据包括：姓名，所属球队，三分球个数，篮板球个数，扣篮成功次数，抢断次数，得分，比赛日期。
2。个人技术数据汇总表。表中反映了每个人的技术数据的累计结果。表羡为：姓名，三分球总数，篮板球总数，扣篮成功总次数，抢断总次数，得分总数，比赛场数。
本系统功能如下：
1。创建存储每常球赛个人技术数据的存储系统（第一次输入个人技术数据时），然后自动创建存储个人技术数据汇总表的存储系统。
2。每场比赛后，添加个人技术数据，然后自动修改个人技术数据汇总表
3。能输出当前的个人技术数据汇总表
4。能输出指定技术项目平均每场数据较高的前三名运动员的姓名，所在队名和平均每场的单项数据。*/
